Docker-Host Connection Example will fail.

[JorheMartinez]

Good evening. Im Jorge
I have been trying to start this example: https://github.com/NetSys/bess/wiki/Hooking-up-BESS-Ports#connecting-vms-and-containers-with-bess-vports
and I have found the following issues trying to connect.

This is my configuration:
dpdk-devbind.py --status:
Network devices using DPDK-compatible driver

0000:02:02.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' drv=igb_uio unused=uio_pci_generic
0000:02:03.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' drv=igb_uio unused=uio_pci_generic

Network devices using kernel driver

0000:02:01.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' if=ens33 drv=e1000 unused=igb_uio,uio_pci_generic Active

One interface for each one of the interfaces, using igb_uio.

The script is as follows:
container_if = VPort(ifname='eth_vport_test', docker='vport_test', ip_addrs=['10.255.99.2/24'])
host_if = VPort(ifname='eth_host', ip_addrs=['10.255.99.1/24'])

PortInc(port=host_if) -> PortOut(port=container_if)
PortInc(port=container_if) -> PortOut(port=host_if)

When running it inside the daemon, it seems to work on the docker side:
root@54ae2c38e5cb:/# ifconfig
eth_vport_test: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.255.99.2 netmask 255.255.255.0 broadcast 0.0.0.0

TX packets 9 bytes 378 (378.0 B)

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 23 bytes 2576 (2.5 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

But not in the Host (Ubuntu 18.04) side:
eth_host: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
ether 96:62:1a:ec:3f:85 txqueuelen 0 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 51 bytes 8203 (8.2 KB)
TX errors 0 dropped 61 overruns 0 carrier 0 collisions 0

although the interface is created, no ip address have been assigned to it,and therefore PING tries will fail.

Any clue on what is happening and how to solve it?
Thank you very much in advance.
